ADDITIONAL INFORMATION
Notice that, by eye, it is even possible that grey is present in the image when it's selected - it does not seem 100% wrong. Nonetheless, on a folder of 20 images I have only 3 that produce a different result. Same thing happens with daily wallpapers.
Comment 1 Nate Graham 2022-08-30 21:36:17 UTC 
This should be addressed by the change we recently made for Plasma 5.26 to prefer the image's highlight color over its dominant color--which indeed tended towards gray. This was one of the issues we were trying to fix.
